Positions remain open! Both PhD and postdoctoral opportunities are available on scientific foundation models. An additional position is also available on AI for regional climate models (jointly with @xavierfettweis.bsky.social). Do not hesitate to apply!

Major publication from my PhD student Josip Brajkovic in the Journal of Hydrology: Regional Studies. Every degree counts! For every 1°C "gains," we'll see an increase in extreme precipitation intensity of +7% and a frequency of /2. @universitedeliege.bsky.social www.news.uliege.be/cms/c_204299...

Extreme rainfall is set to become more intense and more frequent by 2100 in Belgium

This is the future projection of a study conducted by climatologists and hydrogeologists at the University of Liège using their regional climate MAR model.

The melting season over the Greenland ice sheet is starting with likely one of the highest melt event for a month of May. The omega blocking responsible of the drought over Europe advectes very warm air masses along it west size towards the Greenland ice sheet.

A study, using our climate model MAR, lead by my colleague Brice Noel (FNRS) and published in Nature Communications, links the rapid mass loss of Patagonian glaciers to a poleward shift of subtropical high-pressure systems. www.sciences.uliege.be/cms/c_134669...

The polar vortex is "living" its final hours. Its disorganization usually occurs at mid-spring. So, in short, the high pressure system, currently over Western Europe, is not about to move. This suggests a drought in the coming weeks and South => North (heat) or N => S (late frosts) circulations.

📚 New paper alert! 🧵 agupubs.onlinelibrary.wiley.com/doi/10.1029/... 🧪 We present a unique dataset of 465 (!) in situ measurements of the #water_isotopes in vapor up to 1500m above the #Greenland Ice Sheet. 🌍 We demonstrate the use of water isotope profiles to reveal gaps in climate model physics.

Picture of a measurement site on the Greenland Ice Sheet. In the foreground is a fixed‐wing uncrewed aerial system (UAS), looking like a small, light plane with a wing span of 3 m. The UAS is prepared for take-off on a launching system with a high pressure flask that is filled with air through a connected compressor. In the background are white, heated measurement cabin and a turbulence measurement system (eddy covariance) that is connected with a thick bundle of cables to the cabin.

Sous l’effet du réchauffement climatique, les glaciers ont perdu 6 500 milliards de tonnes de glace entre 2000 et 2023, soit l’équivalent de trois piscines olympiques par seconde. Les Alpes et les Pyrénées, les zones les plus touchées, ont vu 40 % de leur glace fondre www.lemonde.fr/planete/arti...

Les glaciers déclinent partout autour du globe, perdant l’équivalent de trois piscines olympiques par seconde

Les Alpes et les Pyrénées figurent parmi les zones les plus touchées, s’étant délestés d’environ 40 % de leur masse en vingt ans, selon une étude parue mercredi dans « Nature ».

Eine neue Studie mit ersten detaillierten Messungen von Gletscherspalten zeigt das Grönland's Eiskappe wahrscheinlich schneller schmilzt als erwartet. insideclimatenews.org/news/0302202...

An aerial view of a South Greenland glacier from a commercial flight. The top third of the image is the thick while Greenland ice sheet with a few grayish rock peaks protruding. In the middle of the picture, coastal mountains and glacier drainages are visible, and in the lower right, blue ocean dotted with dozens of white icebergs.
